RALPH J. FALCONER, OF WASHINGTON, DISTRICT OF COLUMBIA.

SASH-FASTENER.

Specication forming' part of Letters Patent No. 21,328, dated August3-1, 1858i; Reissued. August 16, 1859, No. 798.

To all whom it may concern: ,y

Be it known that I, RALPH J. FALCONER, of l/Vashington, in the county ofWashington and Districtof Columbia, have invented an Improvement inl/Vindow-Fasteners, and that the following is a full, clear, and exactdescription of the principle or character which distinguishes it fromall other things before known and of the usual manner of making,modifying, and using the same, reference being had to the accompanyingdrawings, of which- Figures l and 8 represent an old kind of fasteningupon which my improvement is made. Fig. 2 is a section through the newcatch and hook and the meeting rails of the upper and lower sashes.Figs. 4, 5 and 6 represent the new fastening.

My invention consists in an improvement in that class of windowfasteners, in which the two parts of the fastener are secured upon themeeting rails of the upper and lower sashes in contradistinction tothose fasteners the part or parts of which are let into the meeting railor other part of the sash.

The parts of my fastener are designated as hook and catch. The hook partL is made of metal) of the form and size indicated in the Figs. l, 2, 4,5. It is pivoted at c to the brass plate e, this plate being designed tobe screwed upon the meeting rail of the lower sash. The catch` m is ofthe form'and size shown in the several figures and is a part of thecatch plate n, which is designed to be screwed upon the meeting rail ofthe upper sash. The point of the hook turns around the standard part sof the catch and draws the two sashes together, while the 40 cap part 7'of the catch prevents the sashes from being moved up or down. The formof catch shown in Fig. 3, is that whichhas been hitherto essayed andfound objectionable and in fact should be used only in windows wherethere is but one light of glass in the upper sash; for the followingreason. In unfastening the window, if the point of the hook is not drawnback clear of the meeting rail of the upper sash, on raising the lowersash the point of the hook would strike and injure the bars of the sashabove. To avoid this difficulty I make the catch of the form shown inFigs. 2, 4, 5 and 6. The cap portion m is made to extend lengthwise overthe front edge of the plate n and is united with the plate by thestandard w, thus forming the catch opening a: Hush with the edge of thecatch plate a so that the window cannot be unfastened without hav` ingthe point of the hook entirely clear of the meeting rail of the uppersash and out of the bars above when the sash is raised. The catch m iscast whole with the plate n and I prefer to make the fastener of brass.

What I claim as my improvement in win- `dow fasteners of the class abovespecified, 1s

Extending the cap portion m1 of the catch m over and along the frontedge of the catch plate n to form a catch opening ae flush with the edgeof plate n, so that the window cannot be unfastened without havingl thepoint of the hook a withdrawn entirely clear from the meeting rail ofthe upper sash and out of the way of the bars above when the lower sashis raised.
